Technical Information 2-1 Technical Data For applications outside the following parameters, please consult KPM UK. Hydraulic Data Pressure Fluid Mineral oil, polyol ester and water glycol Use a high quality, anti-wear, mineral based hydraulic fluid when the pressure exceeds 206 bar. In applications where fire resistant fluids are required, consult KPM UK. Fluid Selection allowable temperature range 1000 Ideal working rang

2-1 Technical Data (cont) ♦ Filtration & Contamination Control Filtration The most important means to prevent premature damage to the pump and associated equipment and to extend its working life, is to ensure that hydraulic fluid contamination control of the system is working effectively. This begins by ensuring that at the time of installation that all piping, tanks etc. are rigorously cleaned in a sanitary way. Flushing should be provided using an off line filtration system and after flushing the filter elements should be replaced. ^ Suggested Acceptable Contamination Level The...

2-1 Technical Data (cont) Pump Start Up Precuations Pump Case Filling Be sure to fill the pump casing with clean hydraulic oil through the drain port, filling only the suction line with oil is totally in sufficient. The pump contains bearings and high-speed sliding parts including pistons with shoes and spherical bushes that need to be continuously lubricated. Part seizure or total premature failure will occur very quickly if this procedure is not rigidly followed. Piping & Circuit Checking Check to see that the piping and full hydraulic circuit is completed and that any gate valves etc....

1 : The instant allowable surge pressure as defined by DIN24312. Life and durability of the pump will be affected. *2 : Steady state inlet pressure should be greater or equal to 0.9 bar absolute. *3 : Steady state inlet pressure should be greater or equal to 1.3 bar absolute. The maximum boost pressure should not exceed 10 bar. *4 : SAE E through drive uses the SAE D shaft.

Note: The shaft surface will have a finite life due to wear unless adequate lubrication is provided. #1 Maximum allowable shaft torques are based on achieving an infinite life for a coupling assembly that is lubricated and completely clamped and utilises the full spline/key length as engagement. The following points therefore need to be fully considered:- i) Lubrication of shaft couplings should be in accordance with the coupling manufacturers instructions. ii) The maximum allowable input shaft torque is based on ensuring an infinite life condition by limiting the resultant combined shaft...

2-2 Specifications (cont) Notes: Rated Pressure Pressure at which life and durability will not be affected. Peak Pressure The instant allowable surge pressure as defined by BS ISO 2944:2000. Life and durability however will be shortened. Maximum Self Priming Speed Values are valid for an absolute suction pressure of 0.9 bar. If the flow is reduced and the inlet pressure is increased the speed may also be increased. Maximum Boosted Speed Values stated are the absolute maximum permitted speed for which an increased inlet pressure will be required. Weight Approximate dry weights, dependant on...
